log before restarting services on rewrite_config

PMG::Config::rewrite_config is called from various places (e.g.
pmgmirror for clustered setups, pmgconfig sync --restart for CLI
operations) for rendering the config-templates and conditionally
restarting services.  This patch adds a syslog call for each service
that gets restarted.
